    • A permanent magnet D.C. electric motor includes a stator housing, permanent magnet structure, and an armature assembly. The armature assembly includes a shaft rotatably mounted in the stator housing, lamination structure, first and second coil windings associated with the lamination structure, a first commutator electrically connected with the first coil windings, and second commutator electrically connected with the second coil windings, each of the first and second commutators being generally cylindrical and having a plurality of commutator segments. Certain segments of the first commutator and certain segments of the second commutator are electrically connected. The motor also includes a brush card assembly including a high speed side having first brush structure associated with the first commutator, and a low speed side having a second brush structure associated with the second commutator, and switches for selectively connecting a D.C. voltage in such a way as to cause the armature assembly to rotate at a first speed and a second speed.

    • A jump bar shunt structure 30 includes a base 32 constructed and arranged to be mounted to a substrate and to function as a current shunt; a pair of first legs 34 and 36 integral with the base and being constructed and arranged to be connected between terminals of at least two power devices such as MOSFETs; and a pair of second legs 50 and 52 integral with the base and being constructed and arranged to be connected to a printed circuit board so as to define a current sensing connection. The jump bar shunt structure is a single component that carries high current between two or more power devices and converts current into voltage that is used by the current measurement circuitry. The advantage of the jump bar shunt structure is that no high current (motor current) flows through a control PCB.
    • 跳杆分流结构30包括基座32,其被构造和布置成安装到基板并用作电流分路; 一对第一支脚34和36与该基座成一体并被构造和布置成连接在诸如MOSFET之类的至少两个功率器件的端子之间; 以及一对第二支脚50和52,其与基座一体地构成并被布置成连接到印刷电路板,以便限定电流感测连接。 跳杆分路结构是在两个或更多个功率器件之间承载高电流的单个组件,并将电流转换成由当前测量电路使用的电压。 跳杆分流结构的优点是没有高电流(电机电流)流过控制PCB。
